About US H-1B Specialty Occupation Visa
The H-1B is the principal US visa for foreign professionals in specialty occupations requiring at least a bachelor's degree (or equivalent) in a specific field. Annual cap of 65,000 plus 20,000 advanced-degree-from-US holders. The cap is consistently oversubscribed; USCIS conducts an electronic registration / lottery each March for October-1 start dates. Initial validity of 3 years, extendable to 6, with further extensions if green-card process is in progress. The H-1B is the most significant skilled-worker pathway into the US labour market, and the standard route into the EB-2 / EB-3 employment-based green card.

The O-1 is a US non-immigrant visa for individuals with extraordinary ability in the sciences, arts, education, business or athletics, or extraordinary achievement in film/TV, shown by sustained national or international acclaim. Applicants qualify via a major internationally recognised award (such as a Nobel) or by meeting at least three of eight criteria, plus an advisory-opinion/peer-consultation letter, and a US employer or agent must file Form I-129; self-filing is not allowed. It grants an initial 3-year period with unlimited 1-year renewals, but only while the holder keeps working in the field, and it is not itself a path to a green card or citizenship (the common upgrade is self-petitioning the EB-1A). Costs are high, about USD 17,000-40,000 in year one, largely legal fees, with USCIS processing of 1-6 months or a guaranteed 15 business days via USD 2,805 premium processing. A spouse and children under 21 get O-3 status but cannot work. Holders meeting the Substantial Presence Test are taxed as US residents on worldwide income.

US H-1B Specialty Occupation Visa
- ⚠The H-1B lottery is a hard constraint — selection rate has hovered around 25% per cycle since FY2024
- ⚠Spouse work authorisation (H-4 EAD) requires principal to be on the employment-based green card path with an approved I-140
- ⚠AC21 portability requires 180+ days post-I-140 approval before changing employers without resetting priority dates
- ⚠Country-of-birth (not citizenship) determines green-card priority date — Indian and Chinese H-1B holders face decade-plus EB-2/EB-3 backlogs
- ⚠Status loss on termination is fast — 60-day grace period only
O-1 Extraordinary Ability Visa
- ⚠O-1 is renewable indefinitely but requires ongoing demonstration of extraordinary activities
- ⚠Typical upgrade path: EB-1A (extraordinary ability green card) via self-petition — no employer required
- ⚠Spouse/children on O-3 visa — spouses cannot work under O-3 (unlike E-2)
- ⚠Premium processing ($2,805) strongly recommended for urgent cases
- ⚠3-year initial period with 1-year renewals thereafter
